Zhang Gong Matrix No.: Miao Zhi Shui Circle - the purest environmental enthusiast
Hello everyone, welcome to Miaozhi Water Circle! Today we will continue to learn about the indicator microorganisms in the activated sludge process, and today's protagonist is the bagworm.
Marsupials belong to protozoa, ciliatea, Holotricha, cyclidium. The worm body is long ovate, the fluctuating membrane is large and pronounced, and the small membrane system in the mouthparts is at least half the length of the body and moves slightly to the right.
As a protozoa, the status in the activated sludge process is naturally not as high as the status of active bacteria, but for our operators, it is more difficult to directly observe the type and activity of bacteria to judge the condition of the system, but it is easier to observe the larger, bacteria-feeding protozoa and can be used to indicate the operation of the system.
Next, please follow Zhang Gong to learn the relevant knowledge of the posterior bagworm! Recommended video course, there is a live demonstration video of the bagworm under the microscope! For details, click on the environmental protection water treatment professional is worth collecting! Activated sludge method indicates microorganisms: bagworm
The body of the bagworm is between 25 and 30 microns long, the body is ovoid, the flat head is top without cilia, and the worm body has slightly longer cilia around it. Unlike the tail filarial worm , the peristome has a significant fluctuating membrane up to half the body length , expanding the long cilia when preying. Possum luteum also moves differently from the tail filarial worm, which is characterized by repeated stationary and jumping. Bagworm is easily observed when the organic load of activated sludge is high. Although the environment is similar to that of the tail filariasis, it occurs much more frequently than the tail filaria.

As for the other indicator microorganism that appears in the article, the tail filarial worm, we will focus on its things in the next issue of introduction.
Well, about today's sharing, we will say here, small partners can leave a message in the message area, Xiaobian will reply to everyone in the first time, so that it can be the fastest promotion.
